I tried RL22 in my 270 with the 130gr T-TSX and TSX and got horizontal stringing. I got 3,200fps, safely in my rifle, with it, but could not cure the hs. I tried Win, Rem, Federal and DWM brass, different primers, charge weights and seating depths. I even Dremmeled the old bedding out of the rifle, and re-bedded it. No change.
I switched to H4831SC and IMR4350 and got exceptional accuracy and around 3,150fps.
